Doesn't really apply in this case. While there are some cases where CPU have some unusual fault, those most likely happen in corner cases. What kind of coding do you actually do? I can't really see VS2010, JDev, Eclipse using more than 4 cores. With a 6C/12T machine, you should have enough power to run a dev environment plus a dev DB at the same time. Finally, most games don't use more than 1 thread still.

I noticed your build is also missing SSD. If you got 4K USD to burn and missing a SSD seem weird.
